Event Details

With recent experimental advances, we have entered a new era where quantum matter can be probed far from equilibrium. Yet, non-equilibrium many-body quantum systems are not anywhere as well understood as their equilibrium counterparts. In this talk, I will discuss a generic non-equilibrium setting where many-body quantum systems evolve upon a sudden quench. Examples are provided where quantum fluctuations lead to novel universal dynamics and critical phenomena absent in equilibrium. I will provide recent data from a trapped-ion quantum simulator---mimicking a long-range Ising model---that confirm these predictions. Finally, I will present a new paradigm in quench dynamics where correlation functions decay exponentially while entanglement is diverging, signaling a hidden quantum criticality.
